Polyamines are thought to play a role in the control of inherent or environmentally-induced growth rates of plants. To test this contention, we grew plants of four grass species, the inherently fast-growing Poa annua L. and Poa trivialis L. and the inherently slow-growing Poa compressa L. ...
Pull by hand, or use a hoe to sever the green growth from the roots. Weed killer is often not effective in controlling winter grass, as widely-available commercial products tend to target broadleaved weeds. There are some herbicides which target non-broadleaved weeds such as Poa annua, ...
Poa annua grass: While not the most popular choice among golfers, this turf grass germinates quickly, which can be beneficial for overseeding during the winter months to maintain green color on fairways and roughs in cool-season regions. Fescue grass: This grass requires low maintenance and is...
PennCross Bentgrass Seed - Penn Cross Bent Grass competes with Poa annua on putting greens, tees and fairways. PennCross Bent grass breeding began with 156 vegetatively propagated bentgrasses and was later reduced to 21. These were crossed for turf performance, and the components were tested unde...
to 10 mm wide. The crabgrass seeds overwinter in the ground; and, once the soil remains at 55 degrees Fahrenheit or above for an extended period of time, the seeds germinate. To make the process easier, water the soil beforehand. If control cannot be achieved in spring or early summer, ...
